The third step is to complete the GLM with addition of error. CASESCORECASESCORE 5+2+2=95-2+0= =75-2-2= =65-2+0= =75-2+1= =65-2+1=4

Sum of squares for treatment The effect of the IV!!! Sum of squares for treatment The effect of the IV!!! Sum of squares for error Each term is then squared and summed seperately to produce the sum of squares for error and the sum of squares for treatment seperately. The basic partition holds because the cross product terms vanish.
